How do I time the on state of a signal

[Bloomsoft]

Hi,

I have no LabView experience and have inherited a project. I simply want to record the time that a digital input is true and have the facility to reset the time back to zero for the next run. I found a stop watch VI but cannot modify it so that it:

will run when the signal is true

stop when the signal is false

Has a reset function to reset the accumulated time to zero

Thanks

Hi,

I have written an example VI that should contain the functionality that you require.  I understand that you have little or no experience with LabVIEW, so please don’t hesitate to contact me if anything is unclear in the code.

I look forward to hearing from you.

Regards,

Ian

Thanks Ian but unfortunately I can't open the VI. I am working on version 8.2.1

Hi,

Sorry about that. This VI should run on your system.

Regards,

Ian
